Abstract
In this study, sulphur dye was used for dyeing 100% cotton knitted fabric and the effect of dye concentration and colour shade on ultraviolet protection factor (UPF) was discussed. The results indicated that the UVR absorbency of sulphur dye was not satisfactory. Generally speaking, the higher the dye concentration, the darker the shade of fabric. Nevertheless, it did not affect the UPF of fabric if the absorbency of the selected dye was ineffective.
